Adnan Januzaj has admitted he is spending more time in the gym to improve his wing play.

The Manchester United No.11 was booked for diving for the fifth time in his short Reds career against Arsenal in the FA Cup quarter-final defeat on Monday night and has made just eight starts this season.

A slight debutant at the age of 18, Januzaj has noticeably beefed up since making his first-team bow against Crystal Palace in September 2013.

Still only 20, the Belgian has now revealed how gym work is honing his development.
